Mojoportal Web.config Error 500 on

I just wast a day to figure out what's wrong with the Mojoportal CMS.
Actually its not with the CMS its my IIS Server.
It didn't recognize the <handler> because it missed some requirements to be install in the IIS.

Error

HTTP Error 500.19 - Internal Server Error

Module	IIS Web Core
Notification	BeginRequest
Handler	Not yet determined
Error Code	0x80070021

Config Source:

 1057:       <!-- Handlers for IIS 7.0 Integrated mode -->
 1058:       <handlers>
 1059: 

Go to IIS Manager and click on the website, there is an icon called handlers click that and if it gives you an error on web.config file that's the issue.

"Config Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Fix
Go to "Turn windows features on or off"
Expand "Internet Information Services" > "World Wide Web Services" > "Application Developmetn Fetures" and make sure ASP ASP.net 4.5 3.5 and .Net Fetures and other requirement installed correctly.

Why
Requirement to run Mojoportal is Missing in the IIS
